A teach-in tonight will examine President Nixon's performance in office and the issue of impeachment.

Speakers at the teach-in--which is being sponsored by the New American Movement--will include Kirkpatrick Sale, author of "The World Behind Watergate," and Noam Chomsky, professor of Linguistics at MIT and an antiwar activist.

Arthur MacEwan, assistant professor of Economics, will discuss the relationship between the energy crisis and impeachment.

Mary M. Lassen '75, an organizer of the teach-in, said yesterday that NAM thinks it is "important to present a forum for a leftist discussion of impeachment."

The teach-in will begin at 8 p.m. in lecture room B at the Science Center.
